The influence of the radial runout of the idler on the belt conveyor: within the range of the nationally specified runout, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, causing material toss and pollute the environment. The higher the speed, the more obvious the benefit of the smaller radial runout. my country's national standard stipulates a quantity of 0.7 mm, and the Japanese JIS standard stipulates a quantity of 0.5 mm.
The impact of the flexibility of the roller on the belt conveyor: During the operation of the belt conveyor, the flexibility of the roller is very important. If the flexibility of the roller is not good and the coefficient of rotation resistance is high, the entire belt conveyor system is Need to pay more power, consume more electricity, and sometimes cause the tape to tear, the motor burns out, and in more serious cases, it can cause a fire. Therefore, the selection of rollers with low rotation resistance coefficient (preferably lower than 0.020) is an important part of the design and selection of belt conveyors.
The impact of axial movement on the belt conveyor: my country's belt conveyor manufacturing technology is more and more advanced, but the axis movement is still a topic that needs to be studied, because my country's belt manufacturing technology, belt conveyor installation technology is still in line with the world There is a big gap between the advanced countries, and the tape deviation will often occur. If the axial movement of the roller is large, it will cause the roller to be damaged earlier. Generally, it is better to control the axial movement within 0.5-0.7 mm.
There are five other criteria for judging the quality of rollers:
1. Dustproof performance of roller
2. Waterproof performance of roller
3. Axial bearing performance of roller
4. Impact resistance of roller
5. Service life of roller
